" specification.

tion consists, secondarily, in certain features My invention relates to that kind of valvular contrivance for bath-tubs, &c., in which the means for controlling the egress of water from the tub are formed integral or combined with an overflow-pipe for carrying off the water automatically as it shall rise to a level with its mouth, and thus prevent a flooding of the apartment in case'the cocks, through which the bathing-water is. supplied to the tub, are left open for too long a time.

The main objects of my invention are to provide a simple, efficient, durable, and noiseless contrivance of the description referred to; and to these ends my invention consists, primari ly, in the combination, with a suitable valvular chamber, of a plug or other valvular device, provided with an overflow-pipe, and constructed and arranged so that upon a relative turning of the said plug or valvular device to the said chamber the exit of the water from the tub is either permitted or restrained, and so that any water which may rise in the tub as high as the mouth of the overflow-pipe may be discharged through said pipe and through the valve and its chamber, all as will be hereinafter more fully described; and my invenof construction in the various devices composing the combination, all of which will be hereinafter more fully set forth, and particularly pointed out in the claims.

In the drawings which accompany this specification, Figure l-illustrates a section of a bathtub containing a valvular contrivanee embodying my invention, the latter being shown in elevation. Fig. 2 is a vertical section taken at the line as w of Fig. 1, but omitting the bathtion of the parts of the contrivance separated,

the overflow-pipe being only partly shown. Fig. 5 is a sectional elevation of a modified construction of contrivance embodying my invention, and Fig. 6 is a top or plan view thereof.

In the several figures the Same parts will be found designated by the same letters and num erals of reference. I i g A represents aportion of a bathtub, which is provided, as usual, with stop-cocks a a, 60

through which water from the service-pipes discharge into the tub.

B represents a valve-chamber, formed with a circular flange or rim, 1, that is soldered to the bottom of the tub, and formed with aneck or extension, 2, that passes through the bottom of the tub, and is adapted to be connected, in any of the customary modes, to a pipe for carrying off the waste water. At the lower end of the neck 2 is provided, for the usual purpose, a strainer or sieve, 3, which is preferably cast integral with the neck. The valveseat is tapering and is formed with vertical openings or ports 4 4 4 4, arranged circumferentially and about equal distances apart, and 7 5 the upper end of the valve-chamber is screwthreaded, as shown at 5, and is cut away, as at 6, for purposes to be presently explained. From end to end the vertical valve-chamber extremity, where the strainer is located.

0 designates a plug or valve, tapered to correspond with the taper of the plug or valveseat and adapted to work therein. The plug is likewise formed with ports or openings 7 7 85 7. 7, similar in shape, number, and size to those formed in the plug-seat, and at a point near the upper extremity of the plug is provided a pin or projection, 8,which, when the parts have been put together and are operated, works in 0 It may be made 5 or device B is entirely open, save at the lower a circular flaring disk, 9, having a knurled pe- 10o gether, the threads of the nut engage with those on the chamber, and the flange of the nut comes to a seat or bearing on a circular offset or shoulder, 12, of the plug, thus preventing any longitudinal movement of the plug as well as the overflow-pipe.

in Figs. 1, 2, and 3, the several parts are shown coupled together in condition for use, and in such relationship that an escape of water from the tub through the ports 4 at 4 4 and 7 7 7 7 is impossible, in consequence of said ports being out of register. In other words, the valve or plug is closed, and if a bath is desired to be taken, water from the cooks a a may be admitted into the tub, where it will remain. If, however, the ingress of water is allowed to continue until the fluid shall reach a level with the mouth of the pipe D, any additional water that may enter the tub will flow over the pipe or tube D, and descend through the open way therein and in the hollow plug and chamber down into the waste orsewer pipe. Therefore, no matter how long the cocks a a may be left open, while the valve C is closed there cannot be any flow of water over the top of the tub, because, it will be observed, the discharging capaeity of the pipe D is greater than the charging capacity of both the cooks a a.

Supposing, now, that water having been ad mitted into the tub to the desired level, and the bath to have been taken, and it be desired to discharge the contents, the bather or attendant will grasp the wheel or disk 9, and give a slight turn to thus bring into line the ports 4 1; 4 4 in the valve-chamber and the ports 7 7 7 7 in the plug, whereupon the water will make its exit from the tub through these registered openings and pass out into the waste or sewer pipe connections. Of course, if at any time during this discharge it be desired to check entirely the outflow of the water, the parts are turned back to their first posit-ions, but if it be desired to check only partially the egress of the water to obtain a slow discharge,(which it will be understood is often desirable,) the plug,through the intervention of the overflow tube,is turned back only part of the way,thus abridging the areas of the exit-ports and insuring a less rapid escape of the water. During the turning of the plug within its seat or shell the pin 8 moves around the cutaway 6, and when it arrives at one wall 13 of the same the ports 4 et 1 -1- and 7 7 7 7 are all in line and the water-way therethrough open fully, and

when it reaches the other wall, 14,0f' the cut away or notch the said ports are all out of alignment, and the water-way through them entirely closed. Thus, by means of the pin and notclnthe plug is prevented from turning further than to either wholly close or open the water-way, and one may thus be informed without visional observation and without fecling at the ports as to when the exit-passage is fully closed or opened; and when it is desired to eifect a slow discharge of the water the bather may, by means of the pin and notch, be able to gage pretty accurately the extent of coincidence of the ports or openings, and thus regulate the outflow in accordance with his wishes.

In Figs. 5 and 6 I have shown the overflowpipe D formed with an arched extension, 15, from which projects a stem or shaft, 16,that passes through an eye or bearing, 17, at the inner end of a plate or bracket, 18, which is screwed onto the top of the tub. A handle or key, 19, is made fast to the outer end of the spindle 16, and by this means the plug and overflow-pipe are turned to open and close the water-way through the ports. The bracket 18 is preferably inscribed with the words Open and Shut,as shown,to indicate the directions in which the handle is to be turned to open and close the valve. In the position in which the handle is now represented as occupying, it will be understood that the valve will be held open half-way, and a movement of the handle in one or the other direction will either open or close the valve to a greater extent.

The arrangement for opening and closing the valve shown in Figs. 5 and 6 is shown as a substitute for the means illustrated at Figs. 1 and 2, but it will be understood that so far as the main feature of my invention is concerned bot-h means may be omitted, and the valve operated by grasping and turning the body of the overflow-pipe.

Of course the number, size, and shape of the ports may be changed, and other details of construction of thecontrivance varied without departing from the principle of my invention.

In having the valve rotate or turn, I am enabled to provide a fitting that is simple and durable in construction, and in its operation easy, noiseless, and convenient, wholly avoiding the objections existing to valvular contrivances which have to be lifted and dropped, in the use of which considerable noise and great wear and strain upon the working parts are occasioned, as well as a pounding action on the tub that is detrimental to the soldered scams or joints thereof.

\Vhat I claim as my invention, and desire to secure by Letters Patent, is
